Product description:

The new 650b mountain bikes are the next big thing and the Nashbar Bee’s Knees Single Speed 650b mountain bike is a perfect example of why. The Bee’s Knees Single Speed has the benefits of a 29er without the draw backs. Its bigger wheel size (about 27.5″) means you can roll over stuff that would stop most 26″ MTB’s, but it is smaller and more nimble than a full-size 29er bike. It’s a sweetly spec’d, super simple bike at a value you won’t find anywhere else.

Super simple single speed drive train is ready to tackle nearly any terrain with ease
650b chromoly fork is strong, lightweight and ready to crush some singletrack
Avid BB5 mechanical disc brakes provide plenty of stopping power
Chromoly frame is stiff, lightweight and ultra-durable
Alex XD-Lite 650b wheels are lightweight and trail ready

When we discussed reviewing this bike with Nashbar, they admitted that the gearing is a bit tall for it.They said that they have no problem with us changing things around to suite our riding and gearing preferences. We also plan on testing this bike as a commuter. We figured we might as well put that tall gearing to use before we make those changes we mentioned.

  1. been riding this since summer. love it! why? ADAPTABILITY + FUN FACTOR
    I had some parts lying around which helped.
    1st thing – switched to 29er front wheel.
    2nd – 33×20 gears for shortest chainstay length of 17in
    3rd – wider bar,cushier seat, bb7 calipers
    all I had to buy was a chainring and bar
    Next – trying 29er rear wheel with 700×45 FireCross
